Colorblindness is more common in males than in females because the allele for colorblindness is?

the allele for colorblindness is ressecive NOT dominant. more common in males because they have one x chromosome and women have two, if a deformity is found on the x chromosome in a woman, it can be masked by the other, but still have some sort of side effects, in a male, since he has one, he is effected the most. he has no other genes to mask it.

∙ 12y agoBecause females with two X chromosomes ( XX ) have a statistically better chance of not expressing this recessive trait than men do with a XY sex chromosome pair. No way to stop the expression of this trait without a dominant trait carrying chromosome.

Colorblindness is more common in males than in females because?
the allele for colorblindness is recessive and located on the X chromosomes
Is colorblindness a disability?
Not necessarily. The allele for colorblindness is recessive. For a female, in order to be colorblind she must have to recessive alleles for colorblindness. Example: XcXc would be colorblind. XCXc would be a carrier for colorblindness, but not colorblind. For a male, because colorblindness is a sex-linked gene, he only needs one allele to be colorblind. Example: XcY is colorblind. XCY is not colorblind.
What must occur for a girl to be colorblind?
Each parent must have the recessive allele for colorblindness.
Why can't boys be carriers of colorblindness?
With sex linked traits (the allele is found on the X chromosome) males are either affected or not (they have the defective allele or they don't). Women have two copies of the allele and can be a carrier.
What is the genotype of a carrier of recessive disorder?
A carrier is someone who does not have a disorder but carries the allele on to offspring.

Colorblind male not colorblind female can there kid be color blind?
He will always be colorblind in that case because the defective gene is carried on the "X" chromosome, which males only have one of. You see, the colorblindness gene is recessive, which means if it is paired with a regular color seeing gene it is hidden, and the person can still see the difference between red and green. Because males have only one "X" chromosome, if they get the colorblindness gene from their mother, it will always lead to colorblindness. Side note: Males cannot receive the colorblindness gene from their Father, as he cannot give a "X" chromosome to his son. If he did, his son would be a daughter.
Why do color blindness occur more often in males?
It is rare in females because they have 2 X chromosomes so they have the trait that stops colorblindness, but men have an X and Y chromosome so the Y chromosome does not back up the other X chromosome and makes men have more of a chance to get colorblindness that doesn't mean girls cant get it, just means girls have a better chance to stop it.
Why does color blindness only occur in males?
Here is a simple explanation:Remember that all males have an XY and females have XX, colorblindness is on the X chromosome, and since it is passed on by the X chromosome, this means that females have one good X and one colorblind X . Since colorblindness is recessive, this means the good X can provide the necessary pigments and the female is not colorblind unless she receive two X's that have colorblindness (one from her mother and one from her father), highly unlikely.On the other hand, since the Y has very few genes on it, the pigment missing in the X carrying colorblindness would not be replaced and thus colorblindness would occur in males with the X colorblindness gene from the mother.More info on colorblindnessman pppl on here are smart i didn't know that!!!!! :)

What gene causes color blindness?
i don't know... is there a genetic connection??? Im wondering the same thing. Is there a genetic connection? I concluded that there is not an genetic connection, that dark hair has dark eyes for example. But i do however thing that there is a environmental connection. Both hair and eye color is effected but the environment (sunny, not sunny)
A women wo isn't colorblind but has an allele for color blindness reproduces with a man who has normal vision what is the chance that they'll have a colorblind daughter?
There is no chance for a colorblind daughter because the x-chromosome that comes from the male is normal and then it does not matter which x-chromosome comes from the female because colorblindness is a recessive gene, therefore there is no chance.
